=head1 BUGS |
46 |
|
|
|
47 |
|
|
This module has not yet been extensively tested. Watch out! |
48 |
|
|
|
49 |
|
|
This module does not use the aio_* posix functions because a) linux does |
50 |
|
|
not have aio, b) the existing aio_* functions use pthreads, which are too |
51 |
|
|
buggy for my usage. |
